What are prefixs?

Answer 1

A prefix is a word form that attaches to the beginning of another word or word root, that alters or specifies its meaning.

Examples of prefixes :

re- (to repeat or undo an action) : reconstitute, rerun, reenter

pre- (before) : preview, preregister, prediction

exo- (outside) : exoskeleton, exosphere

in/non/un- (negative, not, or undo) : inactivity, untie, non-perishable, nonfat

Metric system

The International System of Units (SI) specifies a set of unit prefixes known as SI prefixes or metric prefixes. These set the value of a unit in powers of 10.

Answer 2

Prefixes are additions to the beginning of words that influence the meaning of that word. For example, in the word "imperfect," "im" is the prefix that is added to the root word, "perfect."

In this instance, "im" has a negative meaning, changing the meaning of the word "perfect" from its definition meaning "without flaw" to the word "imperfect," meaning, essentially "not without flaw."

Answer 3

Prefixes are a group of letters added at the beginning of a word to change or add to its meaning. They are commonly used in languages like English to create new words or alter the existing ones. For example, adding "un-" as a prefix to the word "happy" changes it to "unhappy," indicating the opposite meaning.
